The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for this little slice of reef.
We’ve got one spot on the radar, and it’s a solid one – Lakey Pipe. The next 16 days are pretty much a non-stop show, starting right from Sunday the 9th of August. Water temps are sitting at a toasty 80°, which is bang on average for this time of year, so no surprises there.
The opening act on Sunday afternoon brings in a 8ft SSW swell with a 16-second period. That’s proper groundswell energy – the combined energy reading is a hefty 2486 (moderate to strong), so you’ll feel the push. The wind is a cross-off from the SSE at 9 mph, keeping things clean but not perfect. It’s a bit marginal on the tide, but the waves will be there.
Now, for the true standout of this whole run, you’ve got to look at Monday the 10th and Tuesday the 11th. Monday morning drops to a 6ft SSW swell, but the period jumps to a very long 16 to 18 seconds. The wind lightens off to just 6 mph from the SE – light breeze, clean conditions. The real magic is Monday afternoon: 8ft, 18-second period from the SSW, with combined energy screaming up to 4129 (very strong). That is a serious, powerful groundswell. For experienced surfers, this is the pick. These long-period swells will line up beautifully on this exposed reef.
Tuesday the 11th gets big – 10ft SSW (16-17s). The energy is off the charts at 4394 and 5798. But here’s the thing: at that size, this break gets too heavy for anyone but absolute experts. The wind is cross-off, but the power is immense. If you’re not a pro, sit this one out.
After that, the week settles into a tasty groove. From Wednesday the 12th right through to Saturday the 22nd, we’re seeing consistent 5ft to 8ft SSW swells with periods in the 14 to 17-second range. Winds stay light to gentle and cross-off – mostly from the SE or SSE at 6 to 9 mph. That’s clean, lined-up reef surfing day after day. The energy stays in the moderate to strong bracket (1121 to 3808). This is a long, reliable window. You’ll have to share the peak though – Lakey Pipe is exposed and crowds are often a factor.
We get another spike around the 23rd and 24th of August. Sunday the 23rd afternoon looks excellent: 7ft SSW, 16 seconds, combined energy of 3593 with light 6 mph S winds. That’s a beautiful cross-off again. Then Monday the 24th morning pulses up to 10ft (17s, energy 4924) – experts only again. The afternoon settles to a more manageable 8ft with an 18-second period and gentle cross-off.
So the bottom line: Lakey Pipe is the only game in town, and it’s a good one. The standout moment is Monday the 10th and Tuesday the 11th for the biggest, cleanest groundswell, but be smart about the size. If you want a solid but less intimidating session, the stretch from the 12th to the 22nd is a dream. Just expect a few others out there with the same idea.
Stay stoked,
Rusty

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
